Even in this century, new — and in this case happy — natural discoveries await:
For the first time in a century, researchers say they’ve identified a new species of wild cat previously unknown to science.
Leopardus tilcayo — or the tilcayo tiger cat — is slender and spotted, with rounded ears. It is smaller than a typical house cat and lives in the Bolivian Yungas, the cloud forest where the Andes mountains meet the Amazon basin. The species was described for the first time in the journal Current Biology on Thursday.
It’s rare to find a new, relatively large mammal. Unsurprisingly, most newly discovered animal species are small in size, said Paola Nogales-Ascarrunz, who co-authored the study and leads a wild cat conservation program called Programa de Investigación de Félidos Bolivia (Bolivian Felid Research and Conservation Program).
“This time, it’s a cat. That’s really novel. And it hasn’t happened in 100 years,” she said. “No one else had named it. No one else had described it.”
The size of the Leopardus tilcayo population is not clear yet.
“We really don’t know how many cats are still in the wild,” said Nogales-Ascarrunz, whose work as a conservationist is funded by National Geographic. “We need science, we need more studies to answer this question, which is actually critical for its conservation.”
